vention has to do chiefly Patented Nov. 30, 1937 UNITED STATES PATENT OFFICE Original application Se ptember 29, 1934, Serial Divided and this application May 14, 1936, Serial No. 79,657

3 Claims.

My invention has reference to a returnable shipping container, and relates more specially to improvements on an apparatus of that kind on which Letters Patent of the United States have 1,970,413, and May 28, 1935, numbered 2,002,625. The present application was divided out of the application for the last named patent.

The present invention involves a construction similar in character to those set forth in said sists of a novel arrangement of chains, specially adapted for use with mentioned.

Other features and advantages of the invention will more fully appear from the following specification, taken in connection with the accompanying drawing, in which;-

Fig. l is a vertical section of the invention on the broken line l-l of Fig. 2.

Fig. 2 is a cross-section on the line 22 of Fig. 1.

Fig. 3 is a detail of view.

Fig. 4 is a side view thereof.

Fig. 5 shows a modified arrangement of the cover locking means.

As mentioned in said former patents, the inwith the transportation of fish and other perishable property requiring refrigeration in transit, as by an ice pack, and occasional renewal of the refrigerant on long a container of the kind the bottom plate It] in plan 7 hauls.

As shown in Figures 1 and 2, the device includes an outer container or barrel 6, fitted with a bottom 1, and closed at the top by a cover 8, preferably of fabric material, and held in place by means detachably connected with the receptacle, such as a hoop. Centrally of the receptacle 8 is a commodity container 9, formed entirely of sheet metal, and provided at its lower end with a bottom section ID, of dished formation, and rigidly held in place by means of rivets H, secured in openings in the flanged portion 'of said bottom section and corresponding openings in the lower end of the container 9.

The bottom plate 10 of abolt I3, passing through openings centrally of said parts, and held in place by a nut 39 on the threaded end of said bolt. The inner container is thereby anchored in place at its lower end. The bottom plate is also provided with feet [5, providing a space between the lower end of the container and bottom of the receptacle 6. Perforations l6 are also provided in the bottom plate 10 to allow for drainage. Similar openings are usually formed in the bottom of the outer receptacle.

The container 9 is also fitted with a cover l1, similar in shape and size with that of the bottom plate l9, and capable-of being used interchangeably therewith. When used as a cover the feet I 5 and perforations can be omitted if desired.

The container 9 is also fitted with a ring I8 on the outside thereof, adjacent to the lower edge of the cover, and secured to the container by eyebolts IS, with which are connected chains 20, passing through openings 2| in the extending above the cover I! and attached ata central point to a ring 24, by means of which the cover is secured from accidental release. This part of the device is provided with a release means consisting of a loop 25 on the end of one of the chains 23, provided at the end with a pin 26, for engagement with one of the links of the chain. When it is desired to remove the cover I! the loop 25 is disconnected from the chain and the chains 23 and ring 24 moved to one side of the cover, without disconnecting the other chains.

By means of the chains 20 the container 9 can be properly positioned to provide a uniform amount of space between the same and the outer container, and when in use the chains 23 can be quickly displaced to permit removal of the cover I! for placing commodities in the container or removing the same. By detaching the chains 20 and releasing the bolt l3 the inner container can be quickly removed from the outer receptacle for any purpose.

In Fig. 5 is shown another arrangement of chains, wherein the loop 25 is eliminated, and three similar chains 23 are united by a triangular wire member 24, replacing the ring 24, and provided at its end with hooks 25 for engagement with the end link of one of said chains. By disconnecting the last named chain the other chains can be dislodged from the cover I! as in the other case. The ends of the member 24 can be is held in place by means 2 secured by a metal seal, if desired, to prevent the purloining of the contents of the container.

What I claim, and desire to secure by Letters Patent, is:

1. A shipping package, comprising an outer container, an inner cylindrical container, including a dish-shaped bottom provided with openings for drainage, a cover of inverted dish-shape for said container, similar to said bottom and adapted for interchangeable use therewith, means for holding said bottom and the bottom of the outer container in spaced, relation, means for detachable connection of the bottom of the inner container with the bottom of the outer container, and connections between the upper end of the inner container capable of adjustment to conform with the spacing between said containers.

2. A shipping package comprising an outer container, providednear its top with openings for the passage of chains, an inner container of metal construction, provided with a top and bottom of corresponding dish-shaped construction,

and usable interchangeably, means for anchorage of the bottom of the inner container with the bottom of the outer container, a band fixed to said inner container near its upper end, chains connected with said band and passing through said openings in the outer container, means for looking said chains to said outer container, and auxiliary chains passing over the cover of the container from said first-named chains and forming a seal for said cover.

3. In a shipping package, an outer container, an inner container anchored in said outer container in spaced relation, detachable means for holding the upper part of said inner container in proper spaced relation with the outer container, a cover supported detachably on said inner container, and a set of chains connected with said inner container, passing over said cover and holding the same in place, one of said chains being detachably connected and removable to permit displacement of said chains..
